Luxury Real Estate: Finding a property as majestic as Castello Sui Lago is a lot like love. You just never know where you’ll find it. This palazzo of extraordinary Italian architecture happens to be in boot-kicking Spicewood, Texas, which is about 45 miles from Austin.

This single-family residence sets on its own peninsula. It is the largest single-family residence in this gated community along Lake Travis. It sets on 3.5 acres with more than 900 feet of private water frontage The 17,000 square-foot contemporary castle, which was built in 2009, has five bedrooms, eight full baths, and a 1,000-bottle wine cellar.

The new owners also will have 6,000 square feet of terraces, a private dock, three infinity swimming pools, a guesthouse, and a seven-car garage on their great estate, which, by the way, we sighted at Christie’s Great Estates.
